現象:
PHCO_36662:
(SR:8606485381 CR:JAGag38374)
ディレクトリのパーミッションが不十分なためディレクトリの削除に失敗して
も、"rm(1) -r"が成功値を返します。
問題点の説明:
PHCO_36662:
(SR:8606485381 CR:JAGag38374)
所有者の検索パーミッションが設定されていないディレクトリに対して"rm(1)
-r"を実行すると、rm(1)は、非ゼロの戻り値ではなく0の戻り値で終了してい
ました。
解決方法:
パーミッションが不十分なためディレクトリを削除できなかった場合は、終了
値2でリターンするようにrm(1)を修正しました。

Category Tags:

Path Name: /hp-ux_patches/s700_800/11.X/PHCO_36662
Symptoms:
PHCO_36662:
( SR:8606485381 CR:JAGag38374 )
rm(1) -r returns success even when directory permissions
caused it to fail.
PHCO_35369:
( SR:8606424905 CR:JAGaf84425 )
rm(1) -r fails to remove directories specified with
absolute path when current working directory is unreadable.
PHCO_31637:
( SR:8606363161 CR:JAGaf23824 )
rm -r dumps core under certain circumstances.
Defect Description:
PHCO_36662:
( SR:8606485381 CR:JAGag38374 )
When rm(1) -r is issued on a directory which doesn't have
search permissions for the owner, rm(1) exits with a
return value of 0, instead of a return value of non zero.
Resolution:
rm(1) is modified to return with an exit value of 2 when
it fails to remove a directory due to insufficient
permissions.
PHCO_35369:
( SR:8606424905 CR:JAGaf84425 )
When rm(1) -r is attempted on a absolute path from a
unreadable current working directory rm(1) aborts and
throws error message as "Cannot remove mountable directory."
It can be reproduced as follows:-
# whoami
root
# mkdir /var/tmp/to_be_removed
# chown lp:lp /var/tmp/to_be_removed
# mkdir /var/tmp/restricted; chmod 700 /var/tmp/restricted
# cd /var/tmp/restricted; su lp
# whoami
lp
# rm -r /var/tmp/to_be_removed
rm: directory /var/tmp/to_be_removed not removed.
Cannot remove mountable directory
# ls -d /var/tmp/to_be_removed
/var/tmp/to_be_removed
# rmdir /var/tmp/to_be_removed
# ls -d /var/tmp/to_be_removed
/var/tmp/to_be_removed not found
The error message "Cannot remove mountable directory" is
misleading.
Resolution:
This defect in rm(1) is fixed by checking if current working
directory is readable before attempting the rm(1) operation
on specified directory. If current working directory is
unreadable then, current working directory is changed to "/"
before attempting rm operation on the specified absolute
path.
The error message is changed to give better information.
PHCO_31637:
( SR:8606363161 CR:JAGaf23824 )
When rm -r is invoked on some directory, under
certain circumstances, rm(1) dumps core. This is
happening while creating the absolute path name
of the directory to be removed. While creating
the absolute path name, the available memory space
in the buffer was being calculated incorrectly
resulting in a array bound write and core dump.
Problem Reproduction:
# cat test.sh
#!/bin/sh
cd /tmp
while read a
do
mkdir $a
/usr/bin/rm -r $a
mkdir $a
cd $a
done << !!

mkdir: cannot create xxxxxxxxxxxxxxxxxxxxxxxx....

Resolution:
While creating the absolute path name,
the available memory space in the buffer
is now being calculated correctly.
Enhancement:
No
